RAIL-JOINT.

To all whomz't may concern: l

I Beit known that I, JOHN DoBRowoLsKI, formery ycitizen `and. inhabitant ofl Russia,

Poland, who have declared `my intention of becoming a citizen of the United States, and va resident of the city of Chicago, county of v- Cook, and Stateof Illinois, have invented certain new and luseful Improvements in Rail-Joints, of which the following is a.

specification, j

My invention` relates to improvements in rail joints, and has for its object the production ,of a rail-joint designed for use in the connection-of a switch tongue with the cooperating rail, ,whereby the switch tongue will. beyieldingly held in a fixed position so ,1 as ,to allow foryielding of the same in order "to, permit of the passage of a train from a swltch or branch track onto a main track `without thereby causing the switch to be opened. f

vAyfurther object is the production of a rail jointas mentioned, which will be of durable and A,economical construction and highlyv eiiclent 1n use.

Other objects will appear hereinafter. i l

E The-invention consists in the combinations and arrangements'of parts hereinafter described and claimed.

:The invention will be best understood by reference to.: the accompanying` drawings i forming a part `of ythis specification, and in which: Y t

and the stationary rail 11, from which and in alinement with which the switch tongue extends.

The joint comprises two reinforcing mem; bers 12 arranged on opposite sides of the rail. 11, the members 12 being formed to snugly embrace the iange and base of the rail, Aeach of said members being provided with a laterally extending base-'portion 13 which is perforated for the accommodation of fasten'y mg spikes. Each of said members 12 is also,

formed with a base portion 14 adapted to engage under the rail, the adjacent inner edges of the base ortions 14 being adapted to overlap, as clearily seen in Figs. 2, 3 and 8. The base portions 14 are formed with extensions 15, and the extensions 15 are provided at their outer ends with lateral extensions 16 which are also perforated for the accommodation of fastening spikes.

To the opposite sides of the switch tongue are applied reinforcin members 17 of a form corresponding wlth the members `12,4

except that the members 17 are not provided with base portions. free, being permitted to slide upon the extensions 15 and 16 of the members 12 in 'the pivotal movement of the switch tongue.

Extending between and connecting the members 12and 17 are elongated resilient bars 18, which engage with dove-tailed slots 19 and 20 provided respectively in the mem-y are elongated leaf springs 22, which are ar-l ranged in slots 23 provided for'tlie receptionA thereof in the extensions 15 of the members 12, as clearly seen in Figs. 2, 3 and 7. The free ends of the springs 22 are formed with upwardly extending lugs 22', which engage `in notches 24 formed at the'under sides of reinforcing members 17 of the switch tongue, said springs 22 being so arranged as to exert pressure upon the members 17 such as will yieldingly hold the switch tongue in the fixed position above referred to.

The members 1 7. arey silient members at both sides of the joint, as

used herein, the joint is rendered applicable for use with switch tongues operating in` either direction, and at the same time the spring members 18 and 22` at one side of the joint will always serve as a cushion in the return movementofthe switch tongue, after the latter has been forced from its iXed position.

` This construction insures a switch ata branch or.` switch. track beingy always closed, so as to avoid the possibility of a fast train travelingv along the main track running into, an open switch. With the construction set forth,l in the event of a train running., from the switch or branch track onto the main. track, the switch tongue will yield under the pressure of the flanges ofthe wheels and' allow the trainto pass,the switch tongues, however, being instantly returned to their closed positions after the passage of thetrain, under' tl'ieinfiuence of the resilient members cooperating therewith. p

The members 12 and 17 are secured to the rails by bolts 25 which pass through said members-and the webs ofthe rails, as clearly seenin. Fig, 8. The bolts 25 are formed at their outer ends with slots 26 all of the bolts coperating with the stationary rail, or the switch. tongue being, engaged: by a single key 27jwhijchisadapted to pass through the slots 26,'.in said bolts,as clearly seen in Fig. 6. In order to holdl the bolts against rotary movement and in a position in which the slots 26 will bein alinement,vthat is,l extend horizonf tally, the bolts. are formed with laterally extending tongues 28 which engage with corA- responding notches 29 provided for the reception. thereof in the openings for said bolts,

inthe reinforcing members at oneside of the rail, ascl'early seen in Figs. 3 and 5.

While I have illustrated and described the preferred, form ofi construction for carrying. my invention intoe'ect, thisis capable of variation and modification without departingI from the spirit of the invention.'v I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the` appended claims.

Havingl described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination of a stationary rail; a switch tongue' arranged in alinement with said rail; and resilient means extending between and connecting said rail and tongue for yieldingly holding the latter in a fixed position, substantially as described.

2. The combination of. a stationary rail; a switch tongue arranged in alinement with said rail; and elongated resilient members extending between and connecting said rail and tongue' for yieldingly holding the latter in a iiXed position, substantially as described.

3. The combination of a stationary rail; a` switch tongue arranged in alinement with said rail; reinforcing members embracing said rail and tongue; and elongated' resilient members extending between and connected with said reinforcing members for yieldingly holding said switch tongue in a fixed position, substantially as described.

4. The combination of a stationary rail; a switch tongue arranged in' alinement with said rail; reinforcing members embracing saidy rail and tongue ;v and elongated resi-lient members extending betweenA and in dove-tail connection with said reinforcing members, for yieldingly holding the. switchy tongue in a fixed position, substantially asfdescribed.

5. The combinationofa stationary rail; a switch tongue; and means for yieldingly holding said switch tongue ina fixed position, said means comprisingresilient members coperating with the bases and sides of said rail and tongue, substantially as described. Y

6. The combination of a stationary rail; a

switchV tongue arranged in alinement' with said rail; reinforcingv members secured to the sides of said` rail, having base portions extending beyond the end of thef rail reinforcing members applied to the sides of said tongue, slidably mounted on said base portions; and elongated resilient members-extending. between and connected with saidf reinforcing-members for yieldingly holding the latter in a Xedposition, substantially as described'. p

In testimonywhereof I have signed my name to this specification iin the presence of two subscribing witnesses.
